Bremen: 767 aircraft - 651 Lancasters, 100 Halifaxes, 16 Mosquitos - of Nos 1, 3, 6 and 8 Groups. 2 Lancasters lost. This raid was part of the preparation for the attack by the British XXX Corps on Bremen. The bombing was on the south-eastern suburbs of the city, where the ground troops would attack 2 days later. The raid was hampered by cloud and by smoke and dust from bombing as the raid progressed. The Master Bomber ordered the raid to stop after 195 Lancasters had bombed. The whole of Nos 1 and 4 Groups returned home without attacking.
